HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 445,986, dated February 10, 1891.

Application filed April 11, 1890. Serial No. 347,514. (No model.)

To whom it may concern:

Be it known that 1, JOHN B. FORESMAN, of Foresman, in the county of Newton and State of Indiana, have invented a new and useful lIay-Press, of which the following is a full,

clear, and exact description.

This invention relates to improvements in the construction of hay-presses in which the baling operation is continuous, and has for its object to provide simple and novel means whereby the bales of hay or straw may be compacted and handed successively and be automatically ejected from the machine.

To this end my invention consists in the construction and combination of parts, as is hereinafter described, and indicated in the claims.

Reference is to be had to the accompanying drawings, forming a portion of this specification, in which similar letters of reference indicate corresponding parts in all of the ures.

Figure 1 is a plan view of the device. Fig. 2 is a side elevation in section, with a vertical guide -frame broken, the section being taken through the longitudinal center line of the machine. Fig. 3 is a longitudinal section of the bale-chamber broken at its rear end and detached from other main elements of the machine, the View exhibiting abale inthe chamber and method of handing the same.

Fig. 4 is an enlarged view of one banding upper portion of a guide-frame on the machine and wire-holding and tension devices thereon. Fig. 7 is a top view of the guideframe and tension-clamp on its side. Fig. 8 is a side elevation in section of the frame, wire-holding spool, and tension-clamp, taken on the line 8 S in Fig. 6; and Fig. 9 is a detached front view of the feeding-throat wings removed from the bale-chamber, the front end throat-sleeve of this chamber being shown broken.

A rectangular frame A is provided for the support of the bale-chamber B and a revoluble feeding-cylinder C. Near the longitudinal center of the frame A a vertical guide frame A is erected, consisting of two opposite guide-posts secured to the horizontal sides of the main frame and held spaced apart at their upper ends by the cap-piece A is shown having strong slatted sides, the top and bottom portions being slatted also and each end open.

At the front end of the bale-chamber a short cylindrical sleeve to is forwardly projected therefrom of a diameter to fit therein, the corners of the bale-chamber being filled in to fit upon the exterior surface of said sleeve Within the sleeve a radial wings I) are formed or secured. Two of these wings are shown in Fig. 9, but more may be employed, if desired. The wings b, when the sleeve (1, is in position, incline inwardly and laterally, after the manner of a propellerblade, forming spirally-inclined planes that are sloped in the same direction, the spaces between the wings affording feeding-throats for introduction of hay or strawinto the balechamber 13. The wings b, joining at their inner ends, are formed into a cylindrical hub that is perforated, as at 0 said circular orifice representing the diametrical centerof the sleeve a.

Upon the frame A, in front of and aligned axially with the sleeve a, a slightly-conical feeding-cylinder O is supported to rotate by the loose engagement of its center shaft 0 with the bracket-box c on the front crossbeam of the frame, and the rear end of said shaft within the center perforation c in the joined wings I). The shaft 0 is secured to the front end of the feeding-cylinder by its insertion through the center hub of the crossbar (I, which spans the opening on the front of the cylinder O, to which said shaft is keyed. Adjacent to the front edge of the wings Z2 conical rollers e are journaled in the same diametrical line across the end of the feeding'c ylinder C, these rollers having their inner pintle ends seated revolubly in perforations of the hub c on the shaft 0, the outer The bale-chamber B may be made with closed side walls; but for economyof inaterlal' journal ends of the rollers entering socketholes in the bosses 6 which are properly located on the cylinder 0 to permit the rear faces of the conical rollers to lie at right angles to the axis of the shaft 0, whereby they will conform to the front edges of the radial wings h, and travel closely to the same when the rollers are revolved with the cylinderv As shown inFig. 2, the ring or sleeve receives the rear end of the cylinder 0, thus 5 permitting the relative adjustment of the rollers e and wings I), as stated.

Upon the cylindrical surface of the feeding-chamber O, near to the upright guideframe A, a projecting rim f is formed or secured, which has a bevel-toothed face proj ected toward the sleeve a, this toothed rim being engaged by a bevel-pinion g, that is mounted on a short shaft g, which is journaled and mounted thereby in a suitable box g that is secured upon the upper side of the frame-timber A, the shaft g having a fork on its free end, which is one portion of anniversal coupling to a power-shaft, (not shown,) through which motion is transmitted from 10 any adequate source of power.

A cross-head 2' is placed between the guideposts A and loosely engaged by its ends therewith, so that reciprocal motion can be given to it. To effect such a movement of 2 5 the cross-head ,a crank 7;, formed on the crossshaft 70'', is connected by a pitman-rod m to the cross-head. Said shaft 70', being journaled in boxes at the upper ends of guide-posts A, projects outside of one post on the side of the 0 machine opposite to where power is applied through the shaft g.

On the projecting end of the shaft is a sprocket-wheel n is mounted and secured, and below said wheel another sprocket-wheel n, of about the same diameter, is attached to the laterally-extended end of a short shaft of, which is journaled in the box 71 that rests on the frame A, the inner end of said shaft having a bevel-pinion 7L3 secured on the same,

40 which pinion may be made to mesh with the bevel-rim f. The box a is integral with or affixed upon the end of the handle-lever it, which is pivoted on the upper surface of the 7 horizontal frame-piece A, its free handle por- 4 5 tion extending forwardly to afford convenient means for throwing the pinion 12. into and out of mesh with the bevel-rim)". A sprocketchain 0 connecting the two wheels 22. n thus transmits power and motion to the cross-head At an equal proper distance from the guideposts A two straight bars of metal made preferably of steel, are secured to project in alignment with the guide-posts and parallel to each other. These being rounded and polished are provided with eye-holes near their arrow-shaped points. The bars 13 are termed needles, and are designed to assist the banding of the hay as it is compressed into bales. To this end there are suitably- 6o spaced holes made in the top and bottom walls of the bale-chamber B for the free passage therethrough of the needles when these are reciprocated.

Upon the cross-beam or cap-piece A wireholding spools a" are revolubly supported by attachment of their pivotal bracket-frames upon the cap-piece at points which. will align the spool-bodies and wire thereon with the needles p. Directly below the wire-holding spools a" a spring-tension clamp-plate s is attached to the side of the cap-piece A said clamp being adapted to restrict the delivery of wire from the spools and afford a proper tension thereto while the baling and handing operations are in progress, the set-screws s by their adj ustment givir g more orless clamping force to the plate 5, as may be required.

In operation the needles are threaded by passing the free ends of the wire on the spools 1' through the eye-holes near their lower ends, and there securing the same removably by bending a loop on the end of the wires, as shown in Fig. 4. The needles 1) are now moved down through the apertures made for them in the bale-chamber 13 until their lower ends project below, as shown in Fig. 3. The

loops on the ends of the wire strands are now drawn upon to afford a proper length of wire below the needles, the wires still remaining in the needle-eyes, the loops being temporarily hooked over the hooks '25, which latter are secured at. a convenient point upon the frame of the machine below the bale-chamber. An upward movement of the needles p is now effected by their connection with the sprocket-chain 0, which may be moved by hand when the first adjustment is made to start baling the hay. The needles 1), being located with their points clearing the interior of the bale-chamber, hold two spaced strands of tie-wire across the chamber vertically. Motion is now communicated to the feeding-cylinder C, and hay introduced through the openings in its front end, the movement of this cylinder being slow enough to permit the easy and safe insertion of hay or straw by the use of a fork. Then the accumulation of hayin the feed-cylinder (J is sufficient to carry a quantity of said material back through the openings between the wings I), which may readily be effected by pressure on the mass with the hay-fork, the rollers 6 will by their revoluble movement axially and orbitally press upon the mass of hay that enters between the wings and cause the hay to slide inwardly on said spirally-inclined wings, and thus be introduced within the bale-chamber B. To render the operation clear, it should be remembered that the front edges of the wings lie near tothe peripheral surfaces of the rollers e, and as the wings incline laterally and rearwardly from these front edges in the direction of the curved arrow in Fig. 5 thewin'gs afford inclined planes with spaces or threats between them. The shaft 0, whercon the in her ends of the rollers c are pivoted, being secured to the cross-bar d, it is evident that the rollers 6 will travel across the front edges of the wings Z) when the cylinder 0 is rotated, which movement should be in the same direction as that in which the wings slope laterally and inwardly. The rolling of the orbitally-moving rollers 6 across the stationary edges of the wings Z) will cause the material-such as hay-that has been introduced between the rollers and wings to be pressed by the rollers against the inclined faces of the wings, so that the latter serve as a backing for the material which will be crowded through the throats between the wings and into the balingchamber. After a sufficientquantity of hay for a bale has been introduced, as stated, the wires will be made to embrace the hay on the rear end and top and bottom sides thereof, the tension on the wires being sufficient to draw them taut. The needle-moving mechanism is now thrown into gear with the bevel-rim f, which will force the needles 1) down through the compacted mass of hay and locate their points, as shown in Fig. 3, thus encircling the bale with two spaced bands that are tightly drawn. hen a bale has been formed and nanded, as described, the operation is completed by drawing a loose bight of wire from each spool sufficient to afford ends for tying the bands. The looped ends being removed from the hooks t are twisted into tight knots with the slackened wire portions. The latternamed are out and new loops formed on their disengaged ends to be placed upon the hooks t, the continued forcing of material into the bale-chamber-B forming another bale in the runner, previously explained.

As previously described, and shown in the drawings, the uniting of the bands which form the hay into bales is effected from the lower side of the baling-chamber. It is apparent, however, that by changing the position of the wire-feeding spools to locate them below the operation of tying the bands can be accomplished from the upper side of the chamber, the baling operation as to disposition of the band-wires being substantially the same.

The formation of bales in the bale-chamber successively will eventually project the one in advance therefrom, and when this occurs the expelled bale is detached from the one following it by manually severing the intervening hay with a proper knife.

It is evident that the operation of baling and handing hay or straw may be continued indefinitely by the methods of construction and operation herein illustrated and described.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. The co mbination, with a frame, a balingchamber, a revoluble feeding-chamber in connection with the bailing-chamber, and mechanism to revolve the feeding-chamber on its axis, of a series of inclined radial wings supported between the baling-chamber and feeding-chamber, and independentlyrevoluble feeding-rollers which are adapted to. lie near the edges of the feeding-wings and force material between them into the baling-chamber, substantially as set forth.

2. The combination, with a revoluble feeding cylinder, a stationary baling chamber which is aligned with the feeding-cylinder, and radial inclined wing-walls that form feeding-throats between the feeding-cylinder and baling-chamber, of conical feeding-rollers pivotally and radially supported in the feedingcylinder near the wing-walls, substantially as set forth.

8. The combinatiomwith a horizontal frame, a stationary balingchamber, a rotary feedingcylinder having an encircling toothed rim, an upright guide-frame at the junction of the feed-cylinder and horizontal frame, and a transverse rovolublyunounted crank-shaft at the top of the guide-frame, of a sprocketwheel on the crank-shaft end, a short transverse shaft movably supported on the horizontal frame below the sprocket-wheel, a pin ion on this shaft which may engage the toothed rim, a sprocket-wheel on the outer end of this short shaft, a sprocket-chain, a crosshead on the guide-frame below the crank-shaft, a pitman between the shaft and cross-head, two spaced depending needles having eyes near their points and secured to the cross-head, and a wiresupplying device, substantially as set forth.
